Figure 4.

Simulation time for a continuous model. x-axis: number of involved nodes. y-axis: Time (in seconds) to simulate a standardized
network with the given number of nodes. Note that in all figures the number of nodes
refers to the number of actual network nodes xi as opposed to the number of nodes in the Boolean tree. To highlight the time complexity
of the different calculation methods, the data series are scaled to coincide for a
network with 4 nodes. Actual simulation times for 4 nodes: Jimena (red) = 0.019 s,
Odefy (blue) = 0.040 s, Squad (green) = 0.046 s. The Additional file 1 explains the definition of the network for a given number of nodes.
